材料：Coastal conditionsThe area described in the volume presents the mariner with a generally adverse combination of navigational factors which are outline below．Local Topography．The Dover Strait is shallow and only is 18 miles wide at its narrowest point．Passage through the strait is further constricted by a series of narrow banks，running NE-SW．The seabed is also littered with wrecks．Natural Conditions．There are strong tidal streams in the strait．Sea level may differ from that predicted and in particular may be lower than expected due to negative tidal surges．The area is also subject to gales and poor visibility．Risk of Collision．There is a high risk of collision caused by the density of vessel traffic on passage through the strait，including deep-draught vessels，and crossing traffic，including ferries and high speed craft．Mine danger area There are two areas off the N coast of France，which remain dangerous because of mines lied in the war of 1939-1945．Due to the lapse of time the risk to surface navigation is now considered to be no more dangerous than that the ordinary risks of navigation but a very real risk still exists with regard to anchoring，fishing or any form. submarine or seabed activity．问题：The crossing traffic in the Dover Strait is probably running ________．A.NE-SWB.SE-NWC.N-SD.E-WIt is implied in the passage that ________．A.mine is not a danger to surface navigation in Dover StraitB.the width of Dover Strait is not so narrowC.the natural conditions in Dover Strait are too serousD.collision with deep-draught vessels or ferries or high speed craft in Dover Strait is hardly avoidableAccording to the passage，the risk of collision in the Dover Strait is caused by ________．A.gales and poor visibilityB.a series of narrow banksC.the density of vessel traffic on passage through the strait and crossing trafficD.a generally adverse combination of navigational factorsIt is inferred that ________．A.although the tidal streams in Dover Strait is strong，there were few ships sunk in itB.most of the wrecks in Dover Strait were deep-draught vessels，ferries and high speed craftC.the wrecks are not dangers to surface navigationD.there were many ships sunk in Dover Strait请帮忙给出每个问题的正确答案和分析，谢谢！
材料：The master of every ship which meets with dangerous ice，a dangerous derelict，or any other direct danger to navigation，or a tropical storm，or encounters sub freezing air temperatures associated with gale force winds causing severe ice accretion on superstructures，or winds of force 10 or above on the Beaufort scale for which no storm warning has been received，is bound to communicate the information by all the means at his disposal to ships in the vicinity，and also to the competent authorities at the first point on the coast with which he can communicate．The form. in which the information is sent is not obligatory．It may be transmitted either in plain language（preferably English）or by means of the International Code of Signals．It should be broadcast to all ships in the vicinity and sent to the first point on the coast to which communication can be made，with a request that it be transmitted to the appropriate authorities．Each Contracting Government will take all steps necessary to ensure that when intelligence of any of the dangers specified in the above paragraph of this regulation is received，it will be promptly brought to the knowledge of those concerned and communicated to other interested Governments．问题：The transmission of messages respecting the dangers specified is free of cost to the ships concerned. The word“intelligence”in the last paragraph means ________．A.witB.mentalityC.wisdomD.informationThis passage is most likely extracted from ________．A.Hague RulesB.Marpol 73/78C.SOLASD.IMDG CodeThe information of dangerous circumstances and conditions specified in the first paragraph shall be transmitted in the passage under the title of ________．A.urgencyB.safetyC.distressD.immediate dangerIt is not essential for the master of a ship which meets with ________ to communicate the information by all the means at his disposal to ships in the vicinity，and to the competent authorities at the first point on the coast with which he can communicate．A.dangerous ice，a dangerous derelict，or any other direct danger to navigation，or a tropical stormB.sub freezing air temperatures associated with gale force winds causing severe ice accretion on superstructuresC.winds of force 10 or above on the Beaufort scale for which no storm warning has been receivedD.any dangers specified in this passage which is not necessary to be promptly brought to the knowledge of d interested Governments请帮忙给出每个问题的正确答案和分析，谢谢！
